Product Description
The Atlas Pro Step On® is Union's highest-performance binding for riders who want all-mountain precision without the strap routine. An Italian-made Forged Carbon spine in the Pro Forged Hybrid highback delivers explosive edge-to-edge power, while the all-new Drive Frame bushing absorbs chatter and keeps energy transferring clean. Built for intermediate to advanced men's riders charging every corner of the mountain.
Product Details
| Highback | S1 Step On® Pro Forged Hybrid: Union's exclusive Forged Carbon spine, which exceeds the strength of injected plastic tenfold and is the only carbon material that can be truly 3D-formed, paired with Duraflex CB nylon (Union's highest fiberglass-content nylon) for durability and an improved binding-to-boot connection. |
| Baseplate | S1 Step On® Duraflex CB: featuring the highest fiberglass content in Union's lineup, lighter, stiffer, and more responsive than Duraflex ST. Designed and manufactured by Union, backed by a Lifetime Warranty. |
| Bushing | Drive Frame w/ Hi-Flex EVA: an all-new Drive Frame design exclusive to the Atlas Pro Step On®, engineered for increased edge response with added damping and shock absorption. Hi-Flex EVA maintains shape over time. |
| Footbed | Non-Stick HP EVA: closed-cell construction with a 100% ice- and waterproof finish; adds damping and shock absorption underfoot. |
| Heelcup | Extruded 3D Aluminum (new for 2026/27): pure aluminum that maintains its true shape under heavy wear and tear, delivering precise heel hold and stability. Backed by a Lifetime Warranty. |
| Hardware | Grade 8.8 Steel: the strongest steel commonly available, used in critical binding components for unmatched strength and reliability. |
| Disk | Step On® 4x2 Disk: compatible with 4x2 mounting · Step On® Channel Disk: compatible with Burton Channel (EST) mounting system. |
| Canting | None |
| Connection System | Burton Step On® Instant Connection™: strap-free, instant heel-to-toe engagement for maximum on-snow convenience and performance. Compatible with Burton Step On® boots. |
